Fans are used in a number of production processes—they play a key role, for example, in extracting gases, cooling down materials or transporting solids at the heart of ventilation systems. Elektror airsystems, headquartered in Ostfildern, Germany, and with two production sites in Waghäusel (Germany) and Chorzów (Poland), is one of the international leaders in the manufacturing of industrial fans and side channel compressors. About 60,000 devices are produced here every year. For the production of its electric motors, used in a variety of fans, the Waghäusel site has been relying on UNI HEAT from EMAG eldec since May 2018: The system ensures precise induction heating of the empty stator housing before the joining process. An interview with Roland Sand, Head of the Production team at Elektror airsystems, about choosing the right supplier, the collaboration with EMAG eldec and the meaning of process reliability follows below:
The academic department of Forming and Joining at TU Chemnitz is expanding its systems technologies for research into complex welding, heat treatment, and forming tasks
Since 29 June 2018, the academic department of Forming and Joining at TU Chemnitz has been using a new induction generator that enables the heating of semi-finished goods consisting of several layers of different materials by applying different frequencies in a targeted manner. This may be useful in particular for the production of plated pipes in the chemical industry or in power plants. 62,000 tons of pipes are produced for these sectors per year in Germany alone.
eldec has been a part of the EMAG Group for over four years. Cooperation among our companies has not only been profitable for us, it has also been beneficial for our customers. Together we have developed several new induction heating processes that integrate the hallmark EMAG multi-function process flow in new production lines. At the same time, eldec generators and inductors can be found in many EMAG joining and laser welding systems. Working together we drive induction heating technology forward, allowing for better performance, shorter heating cycle times and even more precisely regulated heating.
